Be itknown that I, RICHARD lV. BAYLEY, a citizen of the United States,residing at Pittsburg, in the county of Allegheny and State ofPennsylvania, have invented ordiscovered a certain new and usefulImprovement in Air-Brake Apparatus for Cars, of which improvement thefollowing is a speciiication.

The obj ect of my invention is to provide an air-brake apparatus adaptedfor application to drop-bottom or other cars of such special form as toprevent or interfere with the employment of the standard or ordinaryairbrake constructions; to which end my invention, generally stated,consists in the com'- bination of a brake-cylinder adapted tov belocated transversely to a car and above the bottom thereof andabell-crank leverhaving an upper arm'above the bottom of the car coupledto the piston-rod of said cylinder and alower arm coupled to a pull-rodconnected with brake-levers l The improvement claimed is hereinafterfully set forth.

In the accompanying drawings, Figure 1 is a side view in elevation,illustrating; my invention as applied to a drop-bottom gondola car; andFig. 2, a plan or top View of the same.

In the practice of my invention I secure upon the frame 1 of the carabove its sills a brake-cylinder 4, which is located transversely to thecar vand adjacent to one of the inclined ends of its hopper bottom orbot-toms 3, above the drop-bottom or door thereof, so as to standentirely clear of the truck. The brake-cylinder is tted with the usualpiston,

the rod 5 of which is connected at its outer end with one arm ofabell-crank lever 6, journaled in bearings 7 on the frame. The other armof the bell-crank lever 6, whichis located below the carframe, isconnected throughl the intermediation of links, as presently to bedescribed, with pull-rods 11, each of which is coupled to a brake-lever7 of oneof the trucks 2 of the car. The brake-levers 7 and 8 of eachtruck are coupled one to the other by connecting bars or links 9, andeach brakerying the usual brake heads and shoes for applying pressure tothe wheels.

The lower arm of the bell-crank lever G is coupled by a link 13 to alever 14, the opposite end of which isy coupled to the pull-rod 11 ofthe adjacent truck 2. The lever 14 is connected by a rod or bar 15 witha lever 16, which is hung at one end iu a bearing 17 on the frameadjacent to the other truck of the car, and is coupled at its oppositeend to the pull-rod ll of said truck. The link 13 is connected by a rod18 with a chain of the handbrake shaft. Air under pressure is suppliedyto thevbrake-cylinder from a main air or brake pipe 19, in thisinstance through the f intermediation of a triple valve 2l and auX-brake cylinder located above and transversely to a car-frame, abell-crank lever having an arm above the carframe coupled to thepiston-rod of said cylinder, two brake-applying levers carryingA brakebeams and shoes in separate trucks, ya pull-rod coupled to each of saidbrake-'applying levers, two levers, each coupled to one of saidpull-rods, a rod or bar connecting said last-speciied levers, and a linkcoupling the lower arm of the'bellcrank to one of said last-specifiedlevers, substantially as set forth.

lever isalso coupled to a brakebeam l0, car- 5o In testimony whereof Ihave hereunto set -my hand.
